This very rare English set was made in 1936, making it one of the
first sets manufactured. It has a 13 1/2 inch electrostatic CRT.
Except for the grille cloth, a couple of scratches on the top, and
an area just above the CRT, the cabinet is mint. The chassis are
excellent, with no rust.

source is a VCR playing an old test card. The replacement CRT has a
P7 phosphor, causing the image to be blue and not very clear
